The sound quality is adequate for this unit, given the price. They have this weird "feature" where if they don't detect any sound they go into a low power mode, much like a printer does. The problem is they don't always recognize sound. I've had a song or video playing for over a minute before the speakers kick in sometimes. Others, if you have the sound a low to moderate listening level, the speaker will go into this low power mode even if while they're in the middle of producing sound. Turning them on and off tends to fix the problem, but this is ridiculous. I've never seen, or heard of, speakers that do this. I wish I hadn't thrown the box out as I would certainly be returning them if I could.

I got these in 2008 and was pleased with the sound quality (with the exception of the slight buzz when the speakers are on but no audio is playing--as some reviewers have also mentioned). Then, gradually, something happened with the bass...instead of hearing the bass, you'd hear a grainy, booming buzz and not much else. This problem got so bad in recent times, that now the speakers are completely unusable. I don't think I would buy them again; they seem fine at first but it takes some time for the flaws to come out.

Given the size & cost of these speakers, I was very impressed.I needed a compact model to watch tv on my computer, listen to internet radio/podcasts, and listen to music off my phone.I was a bit taken aback at how small these were, but once I plugged them in I was surprised at how much quality sound they packed. These speakers have no problem filling even a large room in my home.As others mentioned, the bass is what you can expect from computer speakers - dance/trance music with a lot of beats does not sound that great, but for every other kind of music these work fine. I typically have them turned up only half way, and the sound is great.My only wish is that these speakers had retractable wires, but oh well.

The good.... speakers are perfect for what I needed (I wanted clarity not earth shattering loudness), and the sound quality is great.The bad... 4 uses and the power adapter died! I tried to buy a new power adapter, but the only place I could find that carried an 18v output, they wanted $33.00 !!!

I can't believe no one else is complaining about this feature.1. Yes the speakers sound decent.2. The hard to turn knob thing has been fixed, it's easier to turn now.BUT the biggest annoyance is JBL has a power saving feature that turns off the speakers when it doesn't hear any noise in about 60 seconds. So you can play a song, it's done and within 1 minute the speakers power off. I then have to reach over and turn the knob to turn the speakers back on. It's fine when there is music playing, the sound is decent and the speakers stay on. But as soon as the music stops the speakers power off. This is especially annoying when I'm chatting online or doing something with intermittent sound. I might not have music in the background but I like hearing that little chime to alert me that someone has sent me an IM. But when the speakers have powered off in less than 60 seconds, I found myself turning these babies on an average of 10+ times a day. I figured this was just a setting that could be adjusted. I called JBL corporate to get more information on this to see if I could disable it or change the timing window to be longer, but they said it couldn't be adjusted.These speakers have been returned. Don't waste your time or money on these.

I like the sound from these speakers - but they keep turning off in the middle of some of my music that features quiet passages. It is very frustrating because the speakers will not stay on during some of the music I want to play for meditation. I would not buy these again, even though the sound is good and they fit great on my desk top, because speakers that won't stay on are a problem.

Please be mindful that output is (only) 6 watt and the lowest frequency response is 80Hz. Compared to cheap & non-premium-brand 2.1 system s(with subwoofer), this product generates weak sound. I understand it is by design. I know I am giving up something for the ability to carry around the speakers. For this price, hmm, I'm not sure if I can really recommend.

Very good sound, nice mids, highs and plenty of volume. I have not experienced the auto power shut off, either my laptop keeps these from going to sleep, or the newest models dont include one of the only downsides to these great speakers.

I bought this for use in my outdoor space. I tried others much more expensive one piece portable speakers and none of them are satisfactory. I guess it's just law of physics that you need to good enough size drivers, and good separation between the left/right speakers. This inexpensive pair of JBL sounds great out of the box, and performed much better in my outdoor space compared to the portable speakers that I tried from Creative Labs, Monsters and Sony.You can be 10-15 ft away and still get a decent sound. Bass is good enough. It does seem to need a little break-in. Initially it sounded very tight but it sounded much better after a few hours of playing.The only complaint I have is that the housing and the material used for the knobs feel a bit cheap. But for $29, there is not really a valid complaint.The audio jack is a cable that ends in a "male" plug. I bought a 25 ft male-to-male extension cable and had no way to plug it into these speakers.Some people complaint about the "Sleep" issue. I haven't experienced that - I am mostly using my iPad's Pandora App with these speakers.Hope that helps.

My previous speakers (which were not JBLs) were ten years old and simply died. They came with the computer that I had bought back then. I was not in any way looking to replace them, but I suppose the time had come for them to give up the ghost. I decided to purchase the JBL Duet IIIs because I have always been partial to the brand going back over thirty years. I have found JBLs to be well-made and they always seem to produce a full, warm, rich sound. I have not been disappointed by this purchase. I like the fact that compared to my previous set of speakers, the Duets take up less space particularly since there is no longer the need for the clunky sub-woofer that always got in the way under my desk. The clarity of the Duets is very good over the entire volume range, but unlike older JBL speakers that full, warm, rich sound (which I always thought was the brand's unique signature) apparently has given way to something that is lighter and airier. Nevertheless, in this price range I think I have received very good value for money.

I had been looking for computer speakers and learning that JBL is a branch of Harman Kardon. I decided to try these.I have owned several HK components during the years and I know it doesn't get more reliable than that.I sure wasn't let down.Eventhough in the product info says aluminum. Don't be fooled, thay are plastic, maybe they are refering to the color.The sound is incredible and the bass is there clear and powerful.These speakers can compete with more expensive ones.The only negatives is the color. I would prefer black and the volume bottom is kind of unconfortable, but over all thay deserve 5 stars.The negative comment on the power being turned off automatically. For me that is a plus.If you want good speakers from a trusted brand at a great price . Look no more.

The sound from these speakers is really good -- when there's sound. After one day, the speakers started going silent for no reason. The sound doesn't come back until I unplug the jack and try again. Then they sound great again until they go silent againI've had very bad luck trying to order computer speakers from Amazon. One product didn't work at all. It's money and time wasted.I strongly recommend going to a computer store for this kind of purchase.

Over the past 6 years, I have bought 4 sets of these speakers for various places in my house. They have decent sound, and are very cute, but I won't buy them again. For two of the sets, the power cord stopped working after about a year. It is pricey to get a new cord. When I got the speakers they were $25, so perhaps a year or two of use would be okay. But now they are double that, so perhaps a different set would be a better value.

Okay, so I know a lot of reviews on here go on like these are audiophile quality, and while they are nice, don't delude yourself, you are still getting what you pay for. While they are above average, the range just isn't there. I listen to almost every genre imaginable and I have to say, if it's bass you are looking for, it's simply not there.Now, let me be clear, I am not a "bass guy". I believe bass should be evenly balanced with the mid and high tones. But with these, the deeper basses simply don't exist. Which is okay, if you are mostly listening to things like rock, singer song writer stuff, even a lot of classical works pretty well. However, if you are planning on putting on some lil' wayne, let me just say, a milli will not be well served. Those songs have a very deep resonating boom boom that are part of what makes the song what it is, and with these, unfortunately, that deep end just doesn't exist in any form.So basically, they are a nice set of desktop speakers to replace a crap set of built in whatevers. For that, they serve their purpose, just don't expect miracles.

I bought two pairs of it. Both stopped working a little over a year. One pair lose one channel. The other pair became completely silent. This product seems have design flaws. And JBL only offer one year warranty, what a shame.

These speakers sound surprisingly good and full. The power saving feature that annoyed a few reviewers, doesn't bother me - when it kicks in, it's only a few seconds. I'm using them with my flat screen TV - they sound much better than the built in ones.My only complaint is that they are not very loud.

I currently own 3 sets of these speakers - one set at work, two at home - and they all have performed wonderfully! Naturally they don't have the bass "oomph" of hi-end bookshelf speakers or a full stereo system, but the Duets are great little speakers. They're unobtrusive and work well with just an iPod attached for background music at a party or a dinner without having to deal with a stereo or portable music system.

I think I've had these speakers for about 7 years and they have worked perfectly the whole time. Amazing sound quality and bass from such little speakers. The volume is excellent as well. Unfortunately, I think I pushed them a little too far recently and blew out the right speaker. I will be purchasing another pair to replace the ones I ruined. Very well worth the price!!

The reason I bought these speakers is because I like listening to Democracy Now while I'm the shower every morning. I used to try and strain and hear the words with my laptop speakers, but this got too irritating. I then tried using the stock external speakers which came with my desktop computer. These worked for a while, but I still had to strain to hear the words at times (the water in the shower is very loud). Then, I purchased these. They meet and exceed my expectations. I could hear every precious word of Amy Goodman on Democracy Now and all her guests. I don't miss a single word anymore. This is truly a blessing. Also, when playing music with them, there is actually a great bass sound for an external speaker set at this price, which does not include a subwoofer. I really do recommend this product and I think you will enjoy it.

I got these four or five years ago, and they're going strong as ever. The sound was strong and clear then, and it still is now, after using them in place of tv speakers for a good year and half, and at least 10 hours of music a week otherwise, and a good few months living in the humid bathroom. Never had any problems, even with as many times as I've knocked them over or accidentally pulled the cord. My sister almost stole them when I moved. If these died tomorrow (which I doubt), I'd buy another pair in a heartbeat.Depending on your musical taste, you can easily annoy your family members with these bad boys. Phenomenal range and power for their size.Only complaint would be that the volume knob can be hard to turn off (not adjust up and down, adjusting is fine, just to turn off). Sometimes I use my teeth, ngl.

I got these guys 6 years ago for my computer from another seller.... they sorta broke and I was left with only 1 speaker...I didnt care cause these speakers kicked butt... recently that same speaker kicked the bucket pretty hard..SO.. I bought them AGAIN here on AMAZON. I swear these are by far the best speakers for a:) the price & b:) the size. They are super easy to set up and the sound quality will surprise you. Clear high end with a pretty sturdy bass quality. I can turn them way up and hear them through out my house.I take these with me on vacation cause i can pack them easily and all I need to do is hook them up to my iPhone and have tunes in my hotel room. Nothing worse then a creepy quite hotel room with a less than useless am/fm radio alarm clock.I read a lot of bad reviews on this product but honestly these are small speakers guys.... they're not meant for your home theater or sound system for giant parties, they're for room or work area when you need some good tunes at a relatively low cost.JBL is a trusted and reliable company... buy these speakers already!

These speakers have greatly enhanced the sound of movies and music on my laptop. The first time I used them I thought, "Wow! Listen to what I've been missing!" I used to put on closed captioning to understand what was being said in some movies. With these speakers, sound is very clear and well balanced. I have not had any distortion. Since the price was so low, I thought the sound might reflect that; I was pleasantly surprised. They are easy to use. The only slight inconvenience is dealing with the cords. I move my laptop (and the speakers) around a lot. The main speaker has three cords: one to connect to an electrical outlet, one to connect to a sound source, and one to connect to the other speaker. Since I move it, the cords get in the way. But a cordless system is probably way more expensive. The speakers themselves are very portable. They are lightweight yet stable and easily balanced, even on a blanket or chair arm. This was definitely a good buy. I'm very satisfied.
